From fddd43e717869d56e481c3fde2d5ee6b5513a1f5 Mon Sep 17 00:00:00 2001 Message-Id: From: Yi Min Zhao Date: Mon, 8 Apr 2019 10:57:25 +0200 Subject: [PATCH] conf: Introduce parser, formatter for uid and fid MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch introduces new XML parser/formatter functions. Uid is 16-bit and non-zero. Fid is 32-bit. They are the two attributes of zpci which is introduced as PCI address element. Zpci element is parsed and formatted along with PCI address. And add the related test cases.
